This invention relates to a heating apparatus and aims to provide a novel compact construction adapted primarily but not necessarily in automobiles.

Another object is to provide a novel construction in which hot water circulating in the cooling system of the automobile, is used as the heating medium. a

A further object is to provide a novel construction using columns affording maximum heating surface and channels for the passage of air.

A further object is to provide a compact construction having a water inlet and a water outlet pipe passing through the columns, a front louver structure connected to the pipes and a plate through which the pipes pass supporting a motor and a fan designed to circulate air about the columns.

The more specific objects and advantages will become apparent from a consideration of the description following taken in connection with accompanying drawings illustrating an operative embodiment.

Figure 11 is 'a cross section taken on the line 1111 of Figure 10,

Figure 12 is a cross section taken on the line 12-12 of Figure 10, and 9 Figure 13 is a cross sectional view'through a further modified form.

Referring first to Figures 1 to 6, the device has a multiplicity of cells 10 that are plate like chambers generally of fiat ring form and 55 each consisting of a pair of thin sheets of copper or theequivalent 11, that are dished intermediate of their inner and outer edges, soldered together marginally at 12, and soldered together at their inner edges at 13, thus providing flat hollow rings. Inaddition, the sheets 11 have openings therethrough from the walls of which outwardly extending flanges 13 project, and which are soldered together at.14. Said sheets 11 have a multiplicity of struck out portions 15. The struck out portions of the difi'erent sheets contact with each other and are soldered togetheras at 16. The structure described constitutes the core, affording interior passages for the circulation of water and spaces between the different cells for the passage of air over their extended exposed surfaces.

vRemovably disposed in the openings afforded by the flanges 13 is a hot water supply pipe 17 and a return pipe 18. Said pipes at their forward ends are closed by caps 19 and 20 screwed thereon and inwardly of the caps they are open along inclined planes as. at 21 and 22, whereby hot water supplied to the pipe 17 discharges at 21 into the interior of the cells and returns through the opening 22 into the return pipe 18. r 1

At the front of the structure, a louvered shutter is provided as at 23 which is riveted or bolted as at 24 to a facing ring 25 which partlytelescopes over the core. Such ring 25 is held in place through the engagement of bolts or fastenings 26 in a water tight manner with the caps 19. In the rear of the louvered shutter 23 an air circulating fan 27 is mounted, said fan operating to draw cold air between the laminations provided by the cells 10 where it is heated and discharge the heated air through the shutter 23, or, if desired the circulation of the air may be reversed and cold air drawn through the shutter and discharged in a heated condition from between the laminations of the cells 10.

The fan 27 may operated from an electric motor as at 28 carried by a mounting disk or plate 29. The pipes 17 and 18 pass through the plate 29 and are surrounded'by reinforcing members 30 and 31. The plates 30 and 31 may be secured in place by bolts 32 which pass therethrough and through the plate 29 and the same are extended as shown in Figures 1 and 6, so that they may serve as an attaching means to mount the device on the dash of the automobile.

In order to avoid leakage, the outermost plates 11 at the front and rear of the device are soldered to or otherwise have waterproof connections with the pipes 17 and 18. Pipes 17 and 18 are adapted to be connected to the water line in the cooling system of the engine of the automobile so that hot water will circulate through the columns. The cells 10 have been shown by way of example only. In lieu thereof, the form shown in Figures 7 to 9 may be substituted. In this form,-each cell may comprise two pairs of plates 40 secured together at their inner and outer edges by solder as at 41 and 42, respectively, opening 43 being provided therethrough for communication with the inlet and return pipes. The innermost plate 40 of each cell is preferably connected together by a spacing member 43 of metal, having radial flutes or corrugations 44 soldered as at 45 to the adjacent plate.

Another modified form is shown in Figures 10 to 12 corresponding to that of the previous form with the exception of the plates 50, corresponding to those at 40 being circumferentially corrugated.

Figure 13 illustrates still another modification and shows that the cell, here designated 60, may be of funnel shape or inclined. Specifically, this cell may be formed as'in any of the previously described views.

Various changes may be resorted to provided they fall within the spirit and scope of the invention.

What is claimed is 1. A heater having a core composed of cells, said cells being each formed of annular dished plates secured together at their inner and outer edges to provide hollow flat rings,

said plates having portions connected together to form water passages, means to space said cells from one another, an inlet pipe extending into one of the water passages and an outlet pipeextending into the other water passage, a shutter, means securing the shutter to the pipes, a fan operable adjacent the shutter to circulate air, a motor to actuate the fan located within the core, and a plate through which the pipes pass supporting said motor.

2. A heater having a core composed of cells, said cells being of ring form and hollow, said cells having portions connected together to form water passages, spacing elements on the cells engaging each other, an inlet pipe exemma? tending into one of the water passages and an outlet pipe extending into the other water passage, a shutter, means securing the shutter to the pipes, a fan operable adjacent the shutter to circulate air, a motor to actuate the fan located within the core, and a plate through which the pipes pass supporting said motor. 1

3. A heater having a core composed of cells, said cells being each formed of annular dished plates secured together at their inner and outer edges to provide hollow flat rings, said plates having portions connected together to form passages, spacing elements on the plates engaging each other, an inlet pipe extending into one of the water passages and an outlet pipe extending into the other water passage, a shutter, means securing the shutter to the pipes, a fan operable adjacent the shutter to circulate air, a motor to actuate the fan located within the core, a plate through which the pipes pass supporting said motor, reinforcing plates through which said pipes pass, and attaching bolts extending through the mounting plate and reinforcing plates.

4. A heater having a core composed of cells, said cells being each formed of annular dished plates secured together at their inner and outer edges to provide hollow flat rings, said plates having portions connected together to form passages, spacing elements on the plates engaging each other, an inlet pipe extending into one of the water passages and an outlet pipe extending into the other water passage, a shutter, means securing the shutter to the pipes, a fan operable adjacent the shutter to circulate air, a motor to actuate the fan located within the core, and a plate through which the pipes pass supporting said motor, caps on the forward ends of said pipes to which said shutter securing means are directly secured.

5'. A heating element comprising a plurality of pairs of spaced annular-shaped dished plates, said plates being secured together at their outer margins and at their inner margins, and outstruck projections on said plates adapted to engage similar projections on adjacent plates for spacing purposes, said plates having openings therethrough for inlet and outlet of the heatin medium, and flanges extendingfrom the p ates about said openings for connection to adjacent flanges.

In testimony whereof I afiix my signature.
